The C43 and C63 differ in their engines and also have certain differences in appearance. Below are the specific details: 1. Appearance: The AMG C43 Coupe model features new spoiler trim panels on both sides of the lower grille. The taillight design of the new car is consistent with that of the AMG C63 model, and it also adopts round quad exhaust pipes. The AMG C63 Coupe has an enlarged grille area, and the latest LED headlights are closer in design to those of the new E-Class. 2. Engine: The 63 series is a classic equipped with the M177, a V8 biturbo engine, which is hand-assembled by technicians with their signatures. Although the displacement of this generation's 4.0-liter biturbo engine is reduced, it still maintains the distinctive tractor-like sound that sets the benchmark. The 45 series, on the other hand, is a compact model equipped with a 2.0T turbocharged M133 transverse engine, named for its extreme power-to-displacement ratio and 450 Nm of torque, achieving initial acceleration performance that closely rivals the 63 series.

There's quite a difference between these two AMGs. The C43 features a 3.0T V6 engine with over 400 horsepower, and its all-wheel-drive system makes daily driving exceptionally stable, even in rainy conditions without worrying about slipping. The C63, on the other hand, packs a 4.0T V8 engine with nearly 500 horsepower, offering pure rear-wheel-drive excitement that's perfect for those who love speed. For my daily commute, the C43 is more worry-free, with fuel consumption around 12L/100km, and it doesn't feel too bumpy over speed bumps. The C63's exhaust note is more explosive, and the acceleration from a red light is truly incomparable, but in city driving, fuel consumption easily exceeds 15L/100km. The space is similar; both can accommodate passengers in the rear seats, and the trunk can fit two suitcases without issue. If your budget allows and you want to occasionally let loose, the C63 is definitely more thrilling; but if you're mainly using it for city commuting, the C43's comfort and practicality are significantly better.

Driving enthusiasts would definitely choose the C63. The thrill of that V8 engine instantly revving up when you stomp on the gas is something the C43 can't deliver, especially the addictive tail-happy fun during mountain road cornering with its rear-wheel drive. While the C43 accelerates quite fast too, its all-wheel-drive system is too stable, making it feel less exciting and more like a luxury sedan. I've tried the steering feel of both models - the C63 is noticeably heavier with road feedback so sharp you can feel every tiny pebble, whereas the C43 is tuned lighter, better suited for stop-and-go traffic. The biggest difference is the exhaust note - the C63 shakes the whole block on cold starts, while the C43's exhaust is more restrained. Maintenance costs don't differ much since they're both AMGs.

The most fundamental differences lie in the engine and drivetrain. The C43 features a 3.0-liter turbocharged V6 paired with 4MATIC all-wheel drive, delivering 490 Nm of torque and a 0-100 km/h acceleration time of 4.7 seconds. The C63, on the other hand, comes with a 4.0-liter V8 and rear-wheel drive, boasting 700 Nm of torque and a 0-100 km/h time that's half a second quicker. In terms of positioning, the C43 is an entry-level performance car that retains more luxury elements, while the C63 is a purebred performance machine with a clear track focus. There's a price difference of several hundred thousand yuan, and the C63 holds its value better in the used car market. Additionally, the tuning potential differs—the C63 can easily surpass 600 horsepower with just an ECU remap, whereas the C43 has more limited potential due to its smaller displacement. For daily commuting, the former is the better choice; for car enthusiasts, the latter is the way to go.
